Recrystallization Law of Ti-IF Steel During Annealing Process

Abstract:

Recrystallization law was investigated at different annealing processes. The results showed that the annealing temperature was a main effect factor on the properties of Ti-IF steel. Nominal recrystallization temperature of the samples was evaluated as 620 °C. Simulated batch annealing was performed by two-stage heating. Determined recrystallization temperature was 660 °C, the recrystallization of samples heated at 660 °C was completed in 68min. For 800 °C, the equiaxial recrystallized grains were obtained. Simulated continuous annealing by rapidly heating to different temperatures, samples were held for 100s and then cooled in air. Recrystallization nucleation was not observed until 660 °C. The occurrence of secondary recrystallization was observed at 900 °C.
